7a-tetraazacyclopent[cd]indene-1,4(2H,3H)-dithione, prepared from 2,3-dialkyl substituted tetraazapentalene derivatives and p-xylylene diisothiocyanate, reacted with N,N′-dialkyl substituted diamines to give macrocyclic compounds by ring closure in good yields. These macrocyclic compounds were converted into desulfurized macrocyclic compounds by treatment with NaBH4 and CF3COOH.
2,3-Bis[(p-isothiocyanatomethylphenyl)methyl]-6,7-dihydro-5H-2a-thia(2a-SIV)-2,3,4a,7a-tetraazacyclopent[cd]indene-1,4(2H) ,3H)-二硫酮,由 2,3-二烷基取代的四氮杂戊烯衍生物和对亚二甲苯基二异硫氰酸酯制备,与 N,N'-二烷基取代的二胺反应,通过闭环以良好的收率得到大环化合物。这些大环化合物通过用 NaBH4 和 CF3COOH 处理转化为脱硫的大环化合物。
